The bins are manufactured using injection-molded, high density polyethylene. They are easy to clean, resistant to rust and corrosion, and impervious to most chemicals. Bins have flat fronts that accept an adhesive type label to allow easy identification. These bins may be ordered with an optional clear plastic window, which increases storage capacity and allows for easy inspection and identification of parts. Six quarter-inch drill holes on the bottom of the bins allow for easy hole insertion for drainage.
